Muck stirring monitoring device and stirring detection method thereof

Abstract

The invention discloses a muck stirring monitoring device and a stirring detection method thereof. The muck stirring monitoring device is located in an excavation cabin and comprises a active stirringassembly and a passive stirring assembly, the active stirring assembly is fixed to the back of a cutter head, the passive stirring assembly is fixed to the rear cabin wall of the excavation cabin, monitoring devices are arranged on the active stirring assembly and the passive stirring assembly, and the monitoring devices are connected with an upper computer. The active stirring assembly and the passive stirring assembly are arranged in the excavation cabin and used in cooperation, and accurate, real-time and bidirectional muck stress monitoring is achieved by arranging active stirring rods and passive stirring rods with the proper tracks and the proper number and arranging the active stirring rods and the passive stirring rods at the same cross section in the middle of the excavation cabin, and the monitored stress value is transmitted to an interface of the upper computer to be displayed, so that the muck condition of the excavation cabin can be monitored in real time on the upper computer.

Description

technical field [0001] The invention relates to the technical field of roadheaders, in particular to a dregs stirring monitoring device capable of stirring dregs in an excavation cabin and a stirring detection method thereof. Background technique [0002] When using a roadheader for tunneling operations, when excavation is carried out under the condition of establishing a pressure balance between the excavation cabin and the face of the tunnel, the excavation cabin is in a closed state due to the existence of high pressure, and the operator cannot accurately unlock it in real time. The internal situation of the excavated cabin, including whether there are large-sized foreign objects, whether there is mud cake in the excavated cabin, the mixing of the dregs in the excavated cabin, and the improvement status of the dregs in the excavated cabin, etc., are greatly affected by the inability to monitor and update feedback in real time. It affects the tunneling efficiency and const...

Problems solved by technology

[0002] When using a roadheader for tunneling operations, when excavation is carried out under the condition of establishing a pressure balance between the excavation cabin and the face of the tunnel, the excavation cabin is in a closed state due to the existence of high pressure, and the operator cannot accurately unlock it in real time. The internal situation of the excavated cabin, including whether there are large-sized foreign objects, whether there is mud cake in the excavated cabin, the mixing of the dregs in the excavated cabin, and the improvement status of the dregs in the excavated cabin, etc., are greatly affected by the inability to monitor and update feedback in real time. It affects the tunneling efficiency and construction period of the roadheader, resulting in an increase in construction costs

[0003] In the published patent CN110849775A, a method for monitoring the viscosity of dregs in the excavation cabin is mentioned. The device and method mention that the viscosity of the dregs in the excavation cabin can be detected by sensors and displayed on the host computer interface in real time, but it cannot be visually judged. Whether there are large-sized foreign objects in the soil, whether there is mud cake in the excavation cabin, etc., and the formation of mud cake cannot be effectively prevented
